Several different BSOD errors

OK so I have replaced the RAM sticks and and that seems to be good. I received a refurbished R9390 from the manufacturer.

The previous 390 didn't click in 100% into the mobo due to the heatsink being in the way. Is the fact the 390 doesn't "click" in 100% detrimental to the cards performance? If it's not I will likely have to buy a better PSU to handle its demands.

In the alternative, I can keep the 390 in the box and try to sell it for a better price. The problem is that the RX 480 is very close to the 390 in performance and it is cheaper brand new. I've only gotten 1 low ball offer for it about 200 dollars under asking, but I'm worried no one will want this card in a couple of months.

I really can't answer about the clicking in . The clicking is a retainer to hold it into place and make sure it doesn't vibrate loose. If the card made complete contact in the slot, there should be no difference in power. I haven't looked it up, but I would suspect your power supply is the minimum recommended for the card. If you do buy another power supply, stick with Seasonic. They are great power supplies, like Corsair AX and HX models, XFX and a few other brands. Seasonic is generally thought of as the best and make some of the other better brand power supplies.

Nvidia just came out with new cards. So, I would suspect AMD will come out with new ones soon to compete with Nvidia. That would make your current cards worth less as they would be a generation older.

Here's the update:

• I sold the 390 since I wanted to get a GPU that works with my 550 power supply.
• As noted, I was still getting memory errors without the 390 installed; bought new RAM and I was able to play Overwatch on low settings with the DirectHD graphics on the mobo.
• Fast forward to today and I bought a brand new RX480. I am now getting atikmpag.sys errors when I play Rocket League. I played a round, and when I pressed "Exit game", it went into a boot cycle where the system would restart, load windows 10, then crash and reset.
• I am confident this brand new card isn't the problem. I will get someone to test it on a new system just in case.
• My guess is either the mobo, PSU, or CPU are the culprit. I will try to do the CPU test again and see what results I get. Is there any way I can test my mobo and PSU?

I tried the driver suggestion. I wiped it with DDU, then installed just the drivers from AMD - newest from July 19 2016. After the restart the computer went into another boot cycle and produced more driver crashes...
I tested the card on my friend's computer, and it was able to boot up the system no problem, and was able to load rocket league and witcher opening screens without issue.
I did the Prime 95 Test. The CPU did max pretty quickly to 95°C-100°C. Nonetheless I kept it going for about 3 hours 5 minutes without any crashes.

I will check my mobo voltage, and see if there is a BIOS update for the mobo since May 17/16.

+ 12.00v : +12.192 v
+ 5.00v: +5.160 v
+ 3.30v: 3.424 v

Your voltages look OK. It seems that your CPU was throttling during the Prime tests. That is entirely too hot for your CPU.

Could you just try putting your card in a different PCIe slot? See if that helps any.

My case is too small, the PSU blocks the other PCIe slot and i physically can't reach it. Should I possibly reapply the thermal paste to the CPU and reseat the fan?

FYI I only have the stock fan on the CPU and the case only comes with one back fan. My apartment has been quite hot recently, whereas when I tested it in the winter/spring the room was colder.
